Research Progress on Wire Arc Additive Manufacturing of Nickel-based High-Temperature Superalloys
摘要
Abstract
Additive manufacturing is an important component of manufacturing information,digitization and intelligence,and arc additive technology has significant advantages in nickel-based superalloy forming.In this paper,the advantages and limitations of different additive manufacturing technologies are compared and analyzed from the aspects of technology clas-sification,development history,standards and technical principles.The arc additive manufacturing process of nickel-based superalloy is introduced,and the advantages and problems of arc additive manufacturing are introduced from three aspects:arc additive process,post-heat treatment of additive parts and numerical simulation of additive forming.The application of arc additive technology in nickel-based superalloy at the present stage is summarized.By improving the droplet transition and making the droplet transition more stable,high-quality forming parts can be obtained.The double wire welding was ap-plied to additive manufacturing to improve the production efficiency of additive manufacturing.After heat treatment,the re-sidual stress of nickel-based superalloy can be reduced effectively,and the microstructure and mechanical properties can be improved.Numerical simulation is used to more accurately analyze the droplet transition and temperature field changes dur-ing layer-by-layer deposition to control the grain changes and element segregation during the solidification process of nickel-based superalloys.关键词
